SPECIFICATION forming part of Letters Patent N 0. 654,782, dated July 31, 1900. Application filed January 29, 1900. erial No. 3,110. (No model.)

To ail whom it may concern: ,1

Be it known that I, ALFRED G. CAMPBELL, a subject of the Queen of Great Britain, residing at Sherbrooke, county of Sherbrooke, Province of Quebec, Dominion of Canada,- have invented an Improvement in LogTurm ing Attachments, of which the following de-, scription, in connection with the accompany, ing drawings, is a specification, like .letters on the drawings representing like parts.

This invention relates to a log-turning at; tachment; and the object of theinventionis to provide a simple and compact applianceof this character constructed to receive logs, sticks, or other objects of like kind of different sizes and to present all parts of the surfaces thereof to knives or cutting mechanism by which the bark can be peeled off uniformly and cleanly from such surfaces or the latter dressed.

The invention involves as one of its features a swinging frame, a shaft carried by said swinging frame, and means upon the shaft to turn a log to present different portions of thelatter to the cutting mechanism, and these,

parts may be of any suitable character, though I have represented the machine in the drawings in one simple and convenient embodi ment thereof.

Figure 1 is a side elevation of the machine:

Fig. 2 is an end elevation of the same as seen from the right in Fig. 1, and Fig. 3 isa plan view of the same. j

The frame for supporting the diiferent parts of the machine may be of any suitable character. It is denoted in a general Way by A, and includes in its construction boxes or casings, as 12 and 13, in which certain of the operating mechanism may be housed to protect the same from flying particles, &c., and which serve as suitable receptacles to contain lubricant in suflicient quantity to apply the same to gearing inclosed therein, as will hereinafter appear. The said bearing-boxes support the rock-shaft14, also sustained by brackets, as 15 and 16, upon the frame A intermediate said boxes. The. rock-shaft in the present case is manually operative,.and it carries a swinging frame of some suitable kind. The swinging frame is represented as consisting of the parallel arms 17 and 18, fixed to the rock-shaft lat and having hubs or bearings at their upper ends to receive the continuouslyrotative shaft 19, carrying suitable means to support and rotate a log or stick, whereby all parts of the latter can be brought into position for action by barking-knives or other fools.- The boxing 12 contains the segmental worm-gear 20, secured to the rock-shaft 14 and adapted to mesh with the worm or screw J21 upon the shaft 22, provided at its outer end with the, wheel 23, equipped with a handle 2et. The two arms 17 and 18, comprising the swinging frame, move in unison, and by graspingithe handle 24: and turning the wheel 23 said frame through the intermediate gearing canbe swung down or up, as may be required. The shaft 19 carries the parallel wheels 25 and 26, shown as peripherally toothed or serrated, this construction serving to afford a firm purchase upon the log and to turn thesame. As the shaft 19 is continuouslyrotative, the wheels 25 and '26 will of course berotated' therewith, so as to turn the log (shown bydotted lines 27 in Figs. 1 and ,2) insuch manner that all parts of the same maybe brought under the operation of the knives. -By swinging the arms 17 and 18 down the attachment may be made to accommodate a log or' stick of a larger size than that repre sented, and the reverse result can be obtained by oppositely moving said arms, whereby the log holder and turner is rendered adjustable. I have deemed it unnecessary to illustrate the knivesor cutting mechanism, for these may be of the kind usually employed in this class of apparatus;

The framing has an offset 28 near the upper right-hand corner thereof which supports the vertical post 29, having an end stop 30, shown as spherical and against which the end ofthe log is adapted to abut, whereby said log is held against longitudinal movement. The spherical end stop will not interfere with the free rotation of the log.

The boxing 13 sustains the shaft 31, provided at its outer end with the pulley 32, around which the belt 33 is passed, one of the runs of saidbelt also travelingagainst the direction or guide roll 34:, supported at the lower end of the bracket 35. Thebelt is connected with a suitable driver upon the main or bark shaft of the machine to which itis screw 36, meshing with the worm-gear 37,

loosely carried by the shaft 14 at what is represented as the left-hand end of the shaft;

The worm-gear hasan elon gated hub or sleeve 38., with which a driver (shown as a sprocketwheel 39) is rigidly united, said sprocket- Wheel being connected y the procket-chaii f 40 with the sprocket-wheel 41 upon the shaft 14, that'carries the log-turning means. The sprocket-wheel is held in place by the bolt 40 and between the head of the bolt and the worm-gear the washer 31 is disposedand serves its usual function. -Theworm-gear referred to is avery simple and convenient mechanism for reducing the speed of the shaft 14, and consequently that of the log-turning wheels and 26,to-the proper extent. The sprocket-39 is concentric with the shaft 31, and hence the continuous motion of the logturning wheels 25 and 26 is in no wise affected when the swinging frame is actuated.

sisting of the arms 17 and 18, will be swung down by the hand-wheel 23 and intermediate connections a proper distance to receive the log, after which said frame-will be returned into position to present said log to the knives.

is inmotion, the log will be rotated by the two toothed-wheels 25 and 26, so as to bring tion by said knives.

pletely removed, the frame can be swung down a very short distance to take 01f said The mechanism for driving the log and place another upon the wheels for treatment. Y Y v The invention is not limited to the precise construction hereinbefore specified, for this may be modified within the scope of the accompanying claims. 7

Having described my invention, what I claim, and desire to secure by Letters Patent-,is'"' 1. In an apparatus of the class specified, a rock-shaft, a worm-gear segment fixed to said rock-shaft, a worm meshing with said segment, ashaftcarrying the worm and provided with means for turning the same, a swinging 'frame rigid with the rock-shaft, a rotative shaft carried by said swinging frame and pro- I videdwith log-turning-meaus,"a driven and l a driving'member fixedly connected with each in threaded engagement with said shaft 31, 1

other and both loose on the rock-shaft, con- E nections between said driving member and the rotative shaft for operating the latter and thereby the log-turning means, and means to actuate said driven member.

- 2. Inan apparatus of the class specified, a rock-shaft, a swinging frame rigid with the rock-shaft and provided with a rotary shaft having log-turning means, a worm-gear and a sprocket-wheel rigidly connected with each other and both loose upon the rock-shaft, a sprocket-chain connecting the sprocket In operation'the log-carrying frame, conwheels, ashaft having'a worm to rotate the worm-gear, a worm-gear segment, ashaft having a worm meshing with said worm-gear segment EtDdPI'OVldBd with means for rotating the same, and boxings to support the wormgearing.
